What is more efficient

[Drakath]

I have a server function that is used by both server and client. When I want to call it via same server script, is it more efficient to simply: myFunction(arg) or triggerEvent("myEventName", resourceRoot, arg) ?

[ALw7sH]

ofcourse "myFunction(arg)"

[Drakath]

ofcourse "myFunction(arg)"

So why triggerEvent is even in MTA?

[WhoAmI]

triggerEvent is for creating custom events, that's completely different thing than calling a function.

[Drakath]

And those custom events call a function. It's basically the same thing.

[WhoAmI]

It isn't. triggerEvent calling an event, which can be attached to function.

You mean you can do stuff like this?

triggerEvent("onPlayerJoin", root, arg)

No, here is explanation...

You should call functions in same file like function(arg) while you have a choice triggerEvent, say you made your own event like "onClientDepositMoney" but this event will not be triggered unless you make it happen manually, in this case, you'll use 'triggerEVent' within SAME file, now when you add "onClientDepositMoney" EXTERNALLY in some other script, the event will be triggered on original script and will call the function from OTHER script too, here is example:

-- atms_c.lua 
function confirmDeposit(acc, money) -- Acc is account of player, got from serverside ofcourse while money is numeric value. 
    if (not money) or (not acc) then return end 
    local prev = getAccountData(acc, "atms.money") or 0 
    setAccountData(acc, "atms.money", tonumber(prev) + money) 
    triggerEvent("onDepositMoney", root, getAccountName(acc), money) 
end 
addEventHandler("onClientGUIClick", deposit_btn, confirmDeposit, false) 
addEvent("onDepositMoney", true) -- Make event trigger-able externally... 

Now some other resource, some other file:

-- logs_c.lua 
function writeLog(acc, money) 
    if (not acc) or (not money) then return end 
    writeLog(acc, "Player has deposited $"..money.."in his bank.") 
end 
addEventHandler("onDepositMoney", root, writeLog)

Wow, that's a really nice feature. Thank you for a nice explanation
